First things first. Safety always. You are unhooking, unconnecting, and moving wiring so unhook BOTH negative battery cables. Chock wheels or set parking brake as you will have the truck out of park at one point.
1) Gather the parts. OEM part # 4839738AA QTY 10 per package (only way they sell them) $ 8.00 + tax = $8.69 for 10 bulbs.
2) Gather a few tools. Including a flashlight.
3) Remove single phillips screw from directly above trash bag hook
4) Pull on the hook and work your way around the trim piece. It is held on with clips and that one screw.
Now it should look like this. Do Not bother unhooking anything from this trim piece. Let it rest on the folded down cup holder.
5) Remove headlight switch assy. Grasp and pull. It is held on with clips only.
Same thing. Just let it hang there, no need to unhook it.
6) Remove TWO screws (stubby phillips) as indicated in picture. They are up inside these two holes at top of trim piece.
Grasp the bottom sides and firmly pull trim piece towards you as in picture below. Also is a great time to put the truck in Manual LOW (get shifter out of the way)
7) locate 4 screws (2 top-2 bottom) each corner that hold cluster. See pic below
Use a thin towell/rag and cover top in steering column so as to not scratch the face up on your cluster. Pull the left side outward first and access the plug on your left behind cluster (reach back there, its a little tight) then Pick up slightly on cluster, push bottom inward and pull top outward. It gets a little tight here to. Use the straight screwdriver to push in on connector lock and pry down with screwdrive popping connector out.
The connector on your left of the cluster you can reach behind and unhook. These connectors are what you are after.
This is the rear of cluster for a look at the location of your plugs.

Now the cluster is in hand, head to your favorite work place, lay down a nice towell, I do not suggest a bath towell if you are married, Sorry at this point you may need a laugh to go along with a few skinned knuckles.
These are what we worked so hard to get to. Now the smaller striaght screwdriver comes in handy to quarter turn and release the bulbs. Needle nose pliers to retrieve them.

NOW FOR THE MATH...... We have 11 bulbs in the cluster, but only 10 new ones. It was simple for me, rather then loose the new ones, I choose to put in all new, but had to guarentee 1 of my old ones was good. So the 12V cordless drill battery come out.
I find one old one that looks great, test good and put it directly behind the keyless entry reciever (THIS WILL BE COVERED IN THE KEYLESS ENTRY DIY), or whatever it is, the "hidden" bulb i am pointing to.

There you have it. Simple as pie. Put it back how you got it out and enjoy being able to see how fast you were going, or what temp you truck is running at.
